Can you become root? All solutions will require root access so if you can't run sudo, can you at least su? Can you run shutdown? How about init? –terdon♦ Apr 12 '14 at 20:04 No, I can't be root. I didn't set Ubuntu's root password! :( –Mohsen Apr 12 '14 at 20:12 @Mohsen Setting a root password would not make any difference. You'd have to run su instead of sudo, but you'd run into the same problem. If you have no way to gain root access, you cannot reboot. –Gilles Apr 12 '14 at 23:45 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote If you have root access, you can try to do this: # echo b > /proc/sysrq-trigger (that will immediately reboot the system without syncing or unmounting your disks.) Unfortunately, I do not think there is a way to reboot without root privileges. share|improve this answer answered Apr 12 '14 at 20:07 dnt 1114 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Linux Hard Reboot
command mostly due to two reason. Either it could be bad blocks on the disk or someone hacked your machine. In this situation first suggestion would be to check /var/log/messages for any disk related http://unix.stackexchange.com/questions/124437/reboot-when-there-is-a-hardware-failure-without-physical-access-to-machine alerts (might see some sense key alerts). tail -n 100 /var/log/messages tail -f /var/log/messages If you notice any disk issues , try any disk utility to confirm this. One option would be use smarttools. You can check smartool option to fix bad blocks. If you already installed it you can take the advantage of that. Next immediate action would be take backup of your system. Good if you already http://linoxide.com/how-tos/inputoutput-error-bad-blocks-how-to-restart-linux/ have it :-). If you have good backup its safe to reboot.If your system was hacked there are chances they might messed up your file and system would not work after reboot. You can also try fsck but it really dont fix most time if it bad block issue. Fsck can fix only if it related to any filesystem related issues. Usually fsck will fail in between as when it try to read the file at bad block. Now if try to reboot , it can also give the same output. You can try init 6. # reboot bash: /sbin/reboot: Input/output error # shutdown -r now bash: /sbin/shutdown: Input/output error If the above reboot commands doesnot work try either forced reboot or shutdown .

Hi, http://iallex.com/inputoutput-error-bad-blocks-how-to-restart-linux/ I usually work on a SLES machine connected through ssh. I wanted to know, is there any command or procedure to know, when the pc got last rebooted and from which IP. generally using the commands last reboot (or) ps -fp 1 only gives us the info input/output error regarding the last time of reboot. But I wanted to know from which IP the reboot command was given. Share this on
